The inquirer asks whether they can voluntarily join the Immediate Supply of Information (SII) system after the year has started and if this would alter their quarterly settlement period. The DGT responds that joining is possible at any time and that the settlement period remains unchanged if the requirements for monthly settlement are not met.
Cuestión planteada Si puede acogerse una vez iniciado el año natural y si su periodo de liquidación coincidirá con el trimestre natural.
La opción voluntaria por el SII puede ejercitarse mediante declaración censal en cualquier momento del ejercicio, surtiendo efecto para el primer periodo de liquidación posterior. Si la adhesión no es el primer día del año, se deben remitir los registros de facturación del periodo anterior del mismo año natural antes del 31 de diciembre. El periodo de liquidación seguirá siendo trimestral si el sujeto pasivo no se encuentra en los supuestos de obligatoriedad de liquidación mensual del artículo 71.3 del Reglamento del IVA.
